SOLUTION 28.4
The
go()
routine launches a new thread that can wake up at any time. If you run the code
repeatedly, you may get varying results, depending on your compiler, your virtual machine,
and the environment in which you are running. The output indicates that in the given run,
the
go()
method retains control through three iterations, printing the list from index 0 to 2:
Mixer1201
ShellAssembler1301
StarPress1401
At this point, the
second
thread wakes up and places
"Fuser1101"
at the beginning of
thelist, bumping all the other machine names down one slot. In particular,
"StarPress1401"
moves from index 2 to index 3.
When the primary thread regains control, the
go()
method prints the remainder of the list,
from index 3 to the end:
StarPress1401
UnloadBuffer1501
